5. Bti (Bacillus thuringiensis israelensis) is a bacterium that controls mosquitoes and black flies in their larval stage. The larvae die after consuming the bacteria and developing a disease specific to them, but harmless to all other forms of wildlife. Bti granular can be broadcast (2.5 to 10 pounds per acre).

6. Identify and eliminate all sources of standing water that collects on your property. Mosquitoes will breed in any puddle that lasts more than four days.

7. Drill holes in the bottom of recycling containers that are left out of doors. Drainage holes that are located on the container sides collect enough water for mosquitoes to breed in.

8. Have clogged roof gutters cleaned on an annual basis, particularly if the leaves from surrounding trees have a tendency to block drains.

9. Turn over plastic wading pools when not in use. A wading pool becomes a place for mosquitoes to breed if it is not used on a regular basis.

10. Turn over wheelbarrows and do not allow water to stagnate in birdbaths.

11. Aerate ornamental pools or stock them with fish. Water gardens are fashionable but become major mosquito breeding grounds if they are allowed to stagnate.

12. Keep swimming pools clean and chlorinated. A swimming pool that is left untended becomes a source of mosquito breeding. Be aware that mosquitoes may even breed in the water that collects on swimming pool covers.
